I don't understand, after clicking Download of official FreeCommander website, I saw the newest version is named with "FreeCommander XE 2017 Build 740 32-bit public", so, why are you guys talking about 754 and 755? Please shed some light about it. BTW, I got the same issue of the Tree Column Width which is the reason forcing me to speak in the forum for the first time.

... there is no download link in the provided link, does that mean that I have to donate before I can download?

You are absolutely right. You need to make donation first, after that you'll get download link. Note, that there are several types of donation - for only one download (only for public, but 64 bit version), for 1 year access (both 32 and 64-bit versions) and permanent access (both 32 and 64-bit versions). Everything in details described here http://freecommander.com/en/donation/
Or you can use public 32 bit version without any donations.
